This book didn’t teach me anything new but I can’t give it too low a rating because it does explain sound concepts. Tell a lie - I learnt what a Rolodex is! One or two chapters are dated but the core concepts are relevant as networking is ultimately about people, not technology. To be fair, the book recommends ditching the Rolodex and migrating to digital solutions.
The first few chapters described why networking is so useful/powerful/important, which dragged on for me because I agreed with everything being said - that’s why I bought the book after all!
I would only recommend this to people who are clueless about networking, perhaps young people still in education.
